Jaribio la Mizizi ya Umoja la Fourier Phillips-Perron (Fourier PP)

Jaribio la mizizi ya umoja la Fourier PP linaongeza jaribio la kawaida la Phillips-Perron kwa kujumuisha vipengele vya Fourier vya masafa ya chini katika sehemu bainifu, hivyo kuwezesha jaribio kuzingatia idadi isiyojulikana ya mabadiliko laini, ya taratibu ya kimuundo katika kiwango au mwelekeo bila kubainisha mapema muda au umbo lake.
